Hi.  I've just installed an Alexor system with a bunch of window/door sensors, several glassbreaks, and couple of motions.  All of the enrollment went well.  However, I've noticed that my motion sensors are either not on or is not working.  I did a walk test last night and attempted to trigger the motion sensors but nothing happens when I walk/jump around them.  I then opened a window - which sounded the sirens (as it should) to make sure I'm not doing something wrong and got a call from the monitoring company a couple of minutes later.  The alarm transmits during a walk test?

 Besides enrolling the motion sensors I've changed the sensitivity (I have no pets in the house) prior to mounting them.  Both motion sensors are set on night mode (37 if I recall correctly).  Is the light supposed to blink every now and then to let me know that they are still powered?  Currently they appear to be completely off as no light blink however long I stare at light with my kids moving around in the room.  Please advise.

Also, is there any way to test the glassbreak sensors without the dedicated tester?  Thank you.

Wireless motion sensors behave differently from wired ones, because of the need to conserve battery power. Once the motion leaves test mode (after 10 trips), it "goes to sleep" for three minutes after each activation. during this time, it sees motion, but it does not transmit a signal to the receiver. If you want to test it in normal operation, stay out of sight for at least three minutes before walking in front of it.

The indicator light follows the same rationale. While it can turn on in test mode, it will NOT light up in normal operating mode. Again, this is to conserve battery power. A door sensor may be tripped a couple of times during a typical day. A motion detector, depending upon the area where it is located, may trip dozens or even hundreds of times a day. If the wireless motion acted just like a hardwired one, you'd be replacing he battery every few weeks.

There is no way to test a glass break detector without the proper tester.

Finally, a walk test will generate calls to the monitoring station if Section 382, Option 2 is enabled ("Alarm Comms During Walk Test").

Thanks Ken for the information.  I know the sensor goes to sleep to conserve power, but when I walked upstairs to check that sensor (no one was upstairs for a long period of time), nothing happened either.  I'll double check again tonight.  And thanks also for the information about section 382 - I best turn that off  Smiley
